High-Speed Vibration

Jeff887 · 02-05-2009, 08:43 PM

When I partially release the throttle, (like trying to maintain constant highway speed) at about 80k and up, I get a strange vibration coming from the rear. It gets worse when I drive faster then that. If I drive up to 120k then throw it into neutral, it vibrates until down about 70k. If I'm driving and putting a load on, it doesn't vibrate... (either foot fully on the gas, or completely off). The vibration is not noticeable at low speeds. I had it "looked over" at the shop today, and they couldn't find anything obvious (u-joints, bearings..etc).
There was a post of this nature "High Speed Vibration" posted by SupraRed in '05 or '06 with very similar symptoms, but no conclusions...

Any ideas?

thanks.
